A Burundi official says talks to bring peace to his country will not resume Wednesday in Tanzania as agreed earlier.

Burundi's ambassador to Uganda Jean Bosco Barege said Tuesday his government has asked for more time to prepare for mediation by Ugandan President Yoweri Museveni in Tanzania. Barege denied reports that the Burundi government had withdrawn from the talks.

Burundi has been rocked by violence since President Pierre Nkurunziza ran for and won a controversial third term in office last year. April's announcement that Nkurunziza would stand for a third term sparked off violent street protests that led to a failed military coup in May and a rebellion. At least 400 people have died from the violence which has escalated since Nkurunziza's re-election in July.
